Check out “Patch-management Interface layers” section of Interfaces, Frontends And Tools page on Git Wiki. There are listed two patch management interfaces, roughly equivalent to Mercurials ‘mq’ extension:
- StGIT (Stacked Git), older of the two, written in Python, uses two snapshots to represent patch
- Guilt (formerly ‘gq’), written as series of bash scripts, series file and the patches (one per file) are stored as plain text file.
- pg (Patchy Git) is deprecated, and no longer maintained.
But if you don’t need more advanced usage, you can use instead “git rebase –interactive” to reorder, squash and split patches. And to manage your branch against current version of upstream, “git rebase” usually would suffice.
